Continuing our policy of bringing our customers the ultimate effectiveness
in fire detection that current technology allows, Series 65 has
been developed from the highly successful Series 60 range of conventional
detectors.
Series 65 incorporates well-proven sensing technologies,
together with advances in materials and electronics technology,
including an IC based on that used in XP95 analogue addressable
detectors.
Having a wide operating voltage of 9-33V, the Series
65 detectors can be integrated into security systems, when used
with a relay base.
The Series 65 wide voltage range consists of ionisation,
integrating ionisation and optical smoke detectors, 4 grades of
heat detector and a range of bases. The detectors are identical
in appearance to Series 60.
wide operating voltage • advanced electronic technology
• flashing LED option • magnetic test switch option • can be used
on security systems • proven detection performance • designed to
meet approvals worldwide
The base has been designed to enable detectors to be plugged in without any need for force, particularly useful when fitting to suspended ceilings. To make it even easier the base has a "one way only fit". All Series 60 bases are lockable.
The detectors are polarity insensitive and bases are easy to wire with an earth connector.
The standard base contains no electronic parts which could be damaged during installation.
Part no. 45681-200
For conventional systems that are designed to operate correctly when one or more detector heads have been removed, a base fitted with a diode on Line 1 is available.
Part no. 45681-201
The sensing part of the detector consists of two chambers - an open, outer chamber and a semi-sealed reference chamber within.
Mounted in the reference chamber is a low activity radioactive foil of Americium 241 which enables current to flow between the inner and outer chambers when the detector is powered up.
As smoke enters the detector, it causes a reduction of the current flow in the outer chamber and hence an increase in the voltage measured at the junction between the two chambers. The voltage increase is monitored by the electronic circuitry which triggers the detector into the alarm state at a preset threshold. An externally visible LED will light up when the detector changes to alarm state.
Part no. 55000-200
An integrating ionisation detector, suitable for use in areas where transient high levels of smoke may be expected, is also available.
Part no. 55000-210
Optical smoke detectors incorporate a pulsing LED located in a labyrinth within the housing of the detector. The labyrinth is designed to exclude light from any external source. At an angle to the LED is a photo-diode which normally does not register the column of light emitted by the LED.
In the event of smoke from a fire entering the labyrinth the light pulse from the LED will be scattered and hence registered by the photo-diode. If the photo-diode "sees" smoke on the two following pulses, the detector changes to the alarm state when the indicator LED will light up. The detector housing is identical to that of the ionisation smoke detector. It is distinguished from this type by having an indicator LED which is clear in quiescent state but produces red light in alarm.
The optical detectors are easy to disassemble and clean without the necessity of returning them to the factory.
Part no. 55000-300
The A1R, BR and CR (rate-of-rise) heat detectors opeartae by using a matched pair of thermistors to sense heat. One thermistor is exposed to the ambient temperature, the other is sealed. In normal conditions, the two thermistors register similar temperatures recorded by the exposed thermistor will increase rapidly. resulting in an imbalance, causing the detector to change inot the alarm state. Rate-of-rise detectors are designed to detect a fire as the temperature increases, but they also have a fixed upper limit at which the detector will go into alarm if the eate of temperature increase has been too slow to trigger the detector earlier.

Mounted in the reference chamber is a low activity radioactive foil of Americium 241 which enables current to flow between the inner and outer chambers when the detector is powered up.
An intergrating ionisation detector, suitable for use in areas where transient levels of smoke may be expected is also available.

The XPlorer heat detectors have a low air flow resistance case made of self-extinguishing white polycarbonate. The device monitor temperature by using a single thermistor network, which provides a voltage output proportional to the external air temperature.
The response to heat increases of the standard heat detectors, Part nos 59000-405 and 59000-406, enables the detector to be utillised as an EN54-5:2000 A2S heat detector, which is equivalent to an EN54-5:1984 Grade 2 detector.
A high temperature heat detector, Part no 59000-415 (with standard base) or 59000-416 (with LED driver base), which has similar characteristics at 25 C but reaches a 55 count at 90 C, is available for use in normal ambient temperatures of up to 55 C. This detector meets the requirements for a CS detector in EN54-5:2000.
Part no 59000-405 (with standard base)
Part no 55000-406 (with LED driver base)
The XPlorer isolator senses and isolates short circuit faults on XPlorer loops. It is loop powered and polarity sensitive. Power and signals to the affected section are restored automatically when the fault is cleared.
Part no. 59000-700
The XPlorer optical detector has a moulded self-extinguishing white polycarbonate case designed to allow free entry of smoke while minimising the effects of dust contamination. Stainless steel wiper contacts connect the monitor to the terminals in the mounting base. Within the case is a printed circuit board, which on one side has the lightproof labyrinth chamber with integral gauze surrounding the optical measuring system. The other side has the address capture, signal processing and communications electronics.
An infrared light emitting diode (IR LED) within the optical chamber is arranged at an obtuse angle to a photo-diode. The photo-diode has an integral daylight-blocking filter. The IR LED emits a burst of collimated light every second. In clear air the photo-diode receives no light directly from the IR-LED. When smoke enters the chamber it scatters light from the IR LED onto the photo-diode in an amount related to the smoke characteristics and density. The photo-diode signal is processed by the optical ASIC and passed to the A/D converter on the communications ASIC ready for transmission when the device is interrogated.
Part no. 59000-605 (with standard base)
Part no. 59000-606 (with LED driver base)
The XPlorer Output Unit provides a voltage-free, single pole, change-over relay output. The change-over contact is operated by an output bit. The Output Unit returns an analogue value of 16 under all conditions.
The sensing chamber of the XP95 ionisation smoke monitor operates in exactly the same way as the Series 60 ionisation smoke detector. The air in the dual chamber is irradiated to produce ions that travel to the positive and negative electrodes and hence create a current flow in the chambers. Smoke entering the outer chamber causes a drop in the current flow and an increase in the voltage measured at the junction between the outer and the inner chambers.
Unlike the Series 60, XP95 does not operate on a threshold basis. The analogue voltage signal produced in he sensing chamber is converted to a digital signal by the electronic circuitry and transmitted to the control equipment on interrogation. The microprocessor in the control equipment then compares the signal with stored data and initiates a pre-alarm or fire alarm as smoke density increases. When the equipment determines that a fire condition exists, it instructs the monitor to switch on its indicator LED and the pre-planned alarm routine is initiated.
Isolators are designed to protect the XP95 loop in the event of a short circuit fault. They divide a loop of fire monitors and ancillary devices into groups of 20 as a rule, so that, in the event of a short circuit, no more than 20 devices will be inoperable. The XP95 isolator has particularly low non-isolating resistance.
The XP95 optical smoke monitor uses the same optical arrangement as the Series 60 optical smoke detector, with an internal pulsing LED and a photo-diode at an obtuse angle. In clear air conditions the photo diode in the XP95 monitor receives no light from the LED and produces a corresponding analogue signal. This signal increases when smoke enters the chamber and light is scattered onto the photo-diode. The signal is processed by the electronic circuitry and transmitted to the control equipment in exactly the same way as in the case of the ionisation smoke monitor.The optical smoke monitor is externally identical to the ionisation monitor but is distinguished by having a clear indicator LED which emits red light when the monitor is in alarm.
The XP95 temperature monitor is distinguishable from XP95 smoke monitors by its low air flow resistance case which allows good contact between the sensing thermistor and the surrounding air.The device monitors temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature. The voltage signal is processed and transmitted to the control equipment in the same way as in the case of the ionisation smoke monitor.
A temperature monitor for use in ambient safe temperatures of up to 50 degrees celsius and which reaches the alarm level at 90 degrees celsius is also available.
The Orbis base is a completely new time-saving design that provides installers with an opening working area and single quadrant terminals, with fixing holes shaped to allowa simple mounting procedure.
Features include two fixing centres, a guide to indicate the length of cable to be stripped, and a continuity link for voltage testing of zone wiring prior to commissioning. Where there is a requirement to align all the LEDs to face the same way, there is a guide mark on the base that allows correct positioning. All bases have a mechanism for locking detectors if required.
Also available is a diode base for use in systems which continue to operate even if one or more detectors have been removed without authorisation; and a relay base.
Orbis heat detectors are suitable in atmospheres with high dust content or where fumes may temporarily be concentrated, such as vehicles loading bays.
The heat detectors have an open-web casing that allows air to flow freely acrossly a thermistor which measures the air temperature every 2 seconds. The stored temperatures are then compared against pre-set values to determine whether an alarm level has been reached.
There are six heat detectors to suit a wide variety of operating conditions.
Static heat detectors respond only when a fixed temperature has been reached. Rate-of-rise detectors have a fixed upper limit too, but they also measure the rate of increase in temperature.
The multisensor smoke detector is a thermally enhanced smoke detector that is a development of the optical detector and goes even further in its capabilities of fire detection.
The optical sensor is influenced by the heat sensing element, making the detector more responsive to fast-burning, flaming fires.
It should be used as the detector of choice in areas of high risk with heat at an early stage of the conflagration and with increased likelihood of unwanted alarms.
The Orbis optical smoke detector's sensing technology makes it significantly different in design from existing optical detectors.
Although the Orbis optical detector operates on well-established light scatter principle, it has a new optical system that gives it even sensitivity to a broad spectrum of fire types, whatever colour smoke is generated. The Orbis optical smoke detector can therefore be calibrated at a sensitivity setting which makes it less likely to generate flase alarms while still meeting international detection standards. The stability of the detector is further increased by the incorporation of drift compensation and the use of algorithms to decide when the dector should change to the alarm state. This greatly reduces the likelihood of a detector producing an alarm as a result of smoke from a non-fire source.
The SL-2000 Series Smoke Duct Detector is the latest innovation for early detection of smoke and products of combustion present in air moving through HVAC ducts in Commercial, Industrial and Residential applications. The SL-2000 is designed to prevent the re-circulation of smoke by the air handling systems, fans, and blowers. Complete systems may be shut down in the event of smoke detection. The SL-2000 is designed and built to meet all local requirements, as well as the NFPA regulations regarding duct smoke detectors. Output terminals are provided for remote accessories such as horns, strobes, remote status indicators and test/reset key switches or push buttons.
